Re: [webauthn] Authentication through only what you are (#1728)

> There isn't a way to request a particular kind of UV, but there is the [`uvm` extension](https://www.w3.org/TR/2021/REC-webauthn-2-20210408/#sctn-uvm-extension) which, if the authenticator supports it, can report after the fact what kind of UV was performed. It may also be possible to use attestation to determine what kind of UV was done. You could then choose to reject assertions with an unsatisfactory UV method if you so wish.

While UVM "exists" nothing implements it, so you can't really rely on this as a relying party in any capacity.
